On this date in 1963, Jorge del Carmen Valenzuela Torres — better known as Chacal de Nahueltoro — was shot at Chillan for murder.

Perhaps Chile’s most recognizable mass-murderer (in the non–political category) the drink-addled young peasant one summer’s afternoon in 1960 took a scythe to his 38-year-old inamorata — and slaughtered all of her five children besides. (None of the children were Valenzuela’s own.)

The horrifying crime became grist for an acclaimed movie, but “the Jackal” was also noted for his dramatic personal turnaround during the two-plus years he spent awaiting his firing squad. In one of those paradoxes of the poor, Valenzuela was a man whose world cared for him only once he was condemned to death: he learned to read and write in prison and embraced spiritual counseling that made the fellow in front of the guns an altogether different creature from the homicidal brute.

While this rebirth made the execution itself controversial, it has also amazingly helped to elevate Valenzuela into the ranks of Latin America’s criminal folk saints. His tomb in San Carlos is crowded with votive offerings in thanksgiving for his intercessions.

(The actor who played Valenzuela in that film later collaborated on a 2005 documentary Bajo el Sur: Tras la Huella de un Asesino Milagroso — exploring the popular devotions that have arisen around his character’s real-life inspiration.)
